摘要

In this paper we present the results of a simple optically transparent enclosure with efficient electromagnetic shielding. Firstly, Indium Tin Oxide (ITO) enclosures are designed for simultaneously providing high transmittance within a visible range and good shielding effectiveness (SE), where weight reduction, small size, and transparency are challenges. In the next step, gold Nano-layer films of various thicknesses are deposited on the patterned ITO glass using the thermal evaporation method. Then, by making a trade-off between optical transparency and SE, an optimized gold film thickness is selected. To assess the proposed approach, the final experimental results of copper, ITO, and gold deposited enclosures are compared. The results showed that a 9nm gold deposited ITO enclosure, provides efficient electromagnetic shielding better than the ITO enclosure (about 15 dB better at the resonance frequency and much closer to the copper enclosure) and at the same time, acceptable optical transparency.
